Hens' eggs typically have a circumference of 5.5 inches and are 2.3 inches long.
Mr Barbouti, a 64-year-old taxi driver from Eastwood, near Southend in Essex, said yesterday: 'My hens have laid big eggs before but when I saw this one I was gobsmacked.
'Harriet is only a young hen, she's about six months old, and has only just started laying eggs.
'She was limping a bit but she was all right. I'm really proud of her. She doesn't seem to have been putting off laying as she's still producing eggs.'
